OF GOLDEN, COLORADO HYPOCHLORITES No Drawing.

charged by, the hypochlorite itself. Prob- 1- ably because hypochlorites directly, and

through the chlorine, (and, perhaps, the nascent oxygen,) which they discharge, attack and rapidly reduce various substances that have or give off, an odor, no one has attempted, heretofore, so far as I know, to perfume them.

I have found that essential oils, in their concentrated state, as well as in proper dilutions, may be added directly to hypochlorites of comparatively high chlorine content, and that when so added they will stay in combination for long periods of time, with the result that when the hypochlorites are put into service, these perfumes overlay, to a considerable extent,the chlorine odor.

Thus, I have mixed a combination of the essential oils of lavender and ofrose and have added the resulting oil directly to a liquid hypochlorite, and, after the lapse of many weeks, have found emanations of the perfuming substances present in the hypochlorite, and evident when the hypochlorite was put into use, and a discharge of chlorine 3 ensued therefrom. I have obtained the same results from the mixture of the-essential oil of rose with a hypochlorite.

An additional beneficial result follows on the combination of essential oils, or of dilutions thereof, with hypochlorites that are in liquid form. As is well known, the deterioration of such hypochlorites is accelerated by their exposure to air. I have found that when an excess of an essential oil or oils is added to a liquid hypochlorite, the excess remains as a film on the top surface. I have Application filed May 11, 1928. Serial No. 277,102.

found that this film interferes with the action of the air on such hypochlorite, and serves to retard deterioration of such hypochlorite.

1. The combination with a liquid hypochlorite, of a fragrant oil that overlies the I hypochlorite. v p

2. The combination with a hypochlorite, of a fragrant substance covering the same and 5.1 constituting a blanket against free access of the air thereto.
